Love the chibi drawing, it is fantastic. I wish can draw better like you. I can't draw hands for crap. They always look deform either the hand looks fat or the fingers look crooked or the thumb is smaller than the fingers. *Eyes shines with hero like pose* I shall make myself better at drawing and singing!!

It is pretty complicated at first, and there are a few things I hate about it, for example, you can't tilt your drawings like you can in Sai. (-_-) But other than that, it's pretty easy once you know how to use it. :3
